If tbe pipe is shown curved in the drawings and no special fittings aze shown, the contractor can assume that the curves can be mad: by deflecdng the joints anth standard lengths of pipc. If shorter lengths aze required, the d:ings will indicate maximum lengths that can be used. '''ye amount of deflection at each pipe joint wheL pipe is laid on a horizontal or vertical curve shall not e,�..eed the manufacturer's printed recommended deflections. Where field conditions recuire deflecdon or curves not anricipated in the drawings, the engineer will determine the methods to be used. When rubber gasketed pipe is laid on a curve, the pipe shall be jointed in a saaight alignment and thea deflected to the cucved alig�unent. Trenches shall be made wides on curves for this purpose. Maxur.wn deflections at pipe joinu and laying radius for various pipe ]engths are specified in the following table, or if not, sliall conform to the manufacturer's and AWWA for the given type of pipe: Maximc�m Permissihle Deflecdon in Laying Mechaaical-7oint Pipe Size ' ' Max.
